@tdietterich @arxiv Apparently arXiv is trying to become the new Nature but without peer-review. That's certainly a highway to hell.

Results (Qwen3-1.7B):

✅ Math reasoning (GSM8K): 81.2% → 86.7% with ProbL2 (+5.5 points)
✅ Code generation (MBPP pass@1): up to 60.8% with neural mirrors
✅ Zero-shot transfer (HumanEval): 53.5% → 62.1% pass@1 (+8.6 points) with ProbL2, NM-GRPO-ES reaches 60.7% using ~30% fewer tokens
✅ Less verbosity: 24–36% shorter generations (big deal for deployment)
✅ More reliable training: variance drops from ±0.7 → ±0.4 (math) and down to ±0.2 with ES (code)

Why this matters:

If you’re running post-training in production, you don’t just want “best run” performance, you want:

➡️ Predictable training
➡️ Better reasoning
➡️ Lower inference cost (fewer tokens)
➡️ And a knob that adapts to task structure (math ≠ code ≠ dialogue)

Conclusion:

Better reasoning doesn’t always need more reward tricks. Sometimes it just needs the right geometry.

@realTrumpNewsX Ukrainian people survives thanks to the military help from the US. One can't destroy tanks and enemy soldiers who come to take his land with just hopes and prayers.

@jmsardain Oh boy that's mean

@evyborov I wonder when they will learn to explain their decisions

A murder verdict in the shootdown of MH17 is only the beginning.

Elon Musk amplifies Russian propaganda about Crimea, Ukraine.

Here's how these lies sound to Ukrainians: "Alaska is seen as a core part of Russia by Russians. Alaska is of critical national security importance to Russia. It's only in the USA because of Tsar Alexander's mistake."

@elonmusk Thanks, Elon!

[Mykola Khandoga @McHandoga]

@elonmusk What other means of not letting someone to keep taking your eyes do you know?

[Mykola Khandoga @McHandoga]

@elonmusk @RenataKonkoly How genocide of Ukrainians looks like peace to you?

[Mykola Khandoga @McHandoga]

@ZelenskyyUa @elonmusk Дякую, пане президенте!

[Volodymyr Zelenskyy / Володимир Зеленський @ZelenskyyUa]

Which @elonmusk do you like more?

[Mykola Khandoga @McHandoga]

@elonmusk It should be decided by the entire country. You can't cut it into pieces - it is in the Constitution.
And who are the "people who live"? Those who had to flee or so were killed during the occupation?

[Mykola Khandoga @McHandoga]

@elonmusk Excellent plan to keep the war going on forever. And a kind invitation to keep annexing more territories.

In 1930s, the Soviets allowed Wehrmacht to use training centers in Kazan (tanks) and Lipetsk (Luftwaffe). This was a prelude to the WW2. It looks like since 2014, German company (and the state?) allowed Russians to use German technology to prepare for what can turn into the WW3.

@YLatynina Ахах, и ведь не дай б-г, ес��и они начнут отвечать за содеянное не по составленному вами порядку 😃

@jmsardain Tried that one. Found it too dark and depressing with no hints on how to describe the QCD vacuum :)

"I held his hand until I realized it was over and he was starting to get cold." Careful reconstruction of murders and rapes committed by Russian soldiers in Bohdanivka, Ukraine.

For thirty years, Germans lectured Ukrainians about fascism. When fascism actually arrived, Germans funded it, and Ukrainians died fighting it.
